Eupoecilia quinaspinalis Zhang & Li , new species

( Figs. 1 a, 2a, 4a)

Type material. Holotype, ɗ, CHINA: Mt. Wuyi (26°54'N, 116°42'E), Fujian Province, 600–740 m, 19– 27.v.2004 (Haili Yu), genitalia slide No. ZX06252. Paratypes: 2 ɗɗ, 2 ΨΨ, same data as holotype.

Description. Adult ( Fig. 1 a): Wing expanse 11.0–13.0 mm. Vertex and frons grayish white. Antenna dark brown. Labial palpus grayish yellow; terminal segment short, drooping. Thorax and tegula grayish yellow. Forewing elongate-subtriangular, costa moderately curved downward distally, apex rounded, termen almost obliquely straight; upperside ground color yellowish intermixed with dark brown; basal half of costa suffused with dark brown forming a costal streak, distal half with two irregular brownish marks, anterior one darker and larger; a large black spot at apex extending over cilia; several black spots present below apex occasionally; median fascia extending from end of costal streak to dorsal 2/5, slightly convex outwards, anterior 1/4 dark brown, posterior 3/4 light chestnut, almost uniformly broad throughout; a large ill-defined, triangularshaped light tawny patch between cell and apex; one black spot on lower angle of cell, another below it on dorsum; underside yellowish brown; cilia light yellowish, black around apex. Hindwing with upperside dark grayish; cilia tinged with grayish, having a fuscous subbasal band; underside slightly grayish. Fore and mid legs dark brown; hind leg grayish yellow, with dark brown on tarsus.

Male genitalia ( Fig. 2 a): Socius slender, with a row of stiff, erect bristles from base to tip. Transtilla with triangular median process thin, acute distally, armed with minute distal spines; transtilla arms broadly oblong. Valva slender; costa gently concave slightly beyond middle; apex rounded; sacculus bearing a semicircular prominence ventro-distally about 1/3 length of sacculus with denticulate ventral edge. Juxta rectangular. Aedeagus moderate, with a short subapical projection 1/6 its length; vesica with a strong, straight subbasal cornutus 1/5 its length, five strong cornuti with broadly flattened base at distal 1/3, numerous minute distal cornuti.

Female genitalia ( Fig. 4 a): Papilla analis broad. Apophysis posterioris short, same length as apophysis anterioris. Sterigma broad, bowl-shaped, notched medially; notch flanked by outward arc-shaped sclerites with denticulate edge. Ductus bursae as long as corpus bursae, with several thorns and large region of wrinkled sclerotization; ductus seminalis originating from anterior 1/3 of ductus bursae. Corpus bursae globular, with dense spines occupying posterior 4/5, with spines forming radiating arc at anterior edge.

Distribution. China (Fujian).

Diagnosis. The new species is similar to Eupoecilia wegneri ( Diakonoff, 1941) in male genitalia, but it can be differentiated from the latter by the costa of the valva being gently concave, the sacculus with a semicircular prominence ventro-distally, the aedeagus with only one subapical projection, and the vesica having five strong distal cornuti ( Fig. 2 a). In E. wegneri the costa of the valva is nearly straight; the sacculus bears a semi-elliptical prominence ( Diakonoff, 1984: fig. 11); the aedeagus has a subapical and a second spiny projection; and the vesica has four strong distal cornuti ( Diakonoff, 1984: fig. 12).

Etymology. The specific name is derived from the Latin prefix quina-, meaning five, and spinalis, meaning spinate, referring to the aedeagus having five strong cornuti at distal 1/3.
